Cyprus launches first underwater archaeological park at ancient port

Cyprus has opened its first underwater archaeological park, offering visitors a glimpse of history at one of the eastern Mediterranean's best preserved ancient harbors. The now-submerged harbor lying off the ancient city-kingdom of Amathus was constructed between 312/311 B.C. and 294 B.C. when Cyprus was the focus of conflict between the two successors of Alexander the Great. It was probably constructed as a naval base because of its narrow entrance, though experts say its combined commercial use cannot be dismissed either.

SpaceX Starship booster 'probably' returning to pad after the explosion -Elon Musk

The Starship rocket booster SpaceX plans to use for an inaugural flight to orbit will "probably" return to its launch mount in Texas next week following a testing explosion on Monday, the company's chief executive, Elon Musk, told Reuters. "Damage is minor, but booster will be transferred back to the high bay for inspections, returning to the launch stand probably next week," Musk said in an email.

Webb space telescope opens door to discoveries still unimagined

The powerful James Webb Space Telescope's inaugural batch of images has opened a new chapter of cosmic exploration, but astronomers say the observatory's most consequential discoveries may well be those they have yet to even imagine. Distant colliding galaxies, gas-giant exoplanets and dying star systems were the first celestial subjects captured by the multibillion-dollar observatory, putting its wide range of infrared-imaging capabilities on colorful display and proving the telescope works as designed.
